error: "unreachable statement in File.close();"

[natie]

I have the following code which is a method that displays the content of a file with the name "File"

 public void DisplayAll()throws IOException
 
    {
               try
            {DataInputStream F = new DataInputStream(new FileInputStream("File"));
            {
                for(;;)
                {
                System.out.println(F.readUTF());
                System.out.println(F.readInt());
                System.out.println(F.readInt());
                }
 
              }
 
            F.close();
            }catch(EOFException eof){}
 
       }
 
 

the error is: "unreachable statement" at the "F.close". what I'm supposed to do?

in line 7

    for(;;)

you have an infinite loop, i.e. there is no exit condition so the F.close() in line 16 can never be reached.
there should be an exit condition for the loop - I would suggest putting the F.close() in the catch EOFException(), e.g.

        DataInputStream F=null;
        try
            {
             F = new DataInputStream(new FileInputStream("File"));
             for(;;)
                {
                System.out.println(F.readUTF());
                System.out.println(F.readInt());
                System.out.println(F.readInt());
 
            }       
         }          
         catch(EOFException eof) { F.close();}
         catch(IOException e) { System.out.println(e) ;}
